, Application october 11, 1934, serial No. 747,862 Renewed March 10, 1937 'I'his invention relates to certain new and useful improvements in a sanitary steel milk cooling cabinet, the object being to provide a cabinet which is eiiicient, economical, durable and one which can. be manufactured very cheaply.

Another object of my invention is to provide a milk cooling cabinet especially adapted to be used by the milk producer who cannot obtain a daily ice delivery; whereby the milk producer can store a quantity of ice, at least 400` lbs., usually a weeks supply; whereby the farmer can obtain a much lower price per hundred pounds by purchasing the ice in rlarge quantities; Whereby the cost of delivery to the milk producer is greatly reduced by requiring only one or two deliveries per week instead of the costly daily deliveries; whereby the storage of ice will maintain l the milk at the proper temperature cheaply until it can be delivered, without danger of spoiling or becoming harmed by the growth of bacteria. Another object of my invention is to provide a cabinet with a central water compartment on each side of whichv is arranged an ice compartment having an inclined bottom for maintaining the cakesv of vice in said compartment against the side wall of the water compartment, and in a dry condition, whereby I am able to maintain the water in the water compartment at a temperature of from 7 to 10 degrees F. lowerLby having the surface of the ice come in direct con-` tact with the walls oi the center Water container than it is possible with other types of cabinets in which the ice is disposed in` an icecompart-l ment and is not kept in a dry condition and maintained in close contact with. the walls of` Other and further objects and advantages ofr the invention will be hereinafter set forth and 504 the novel features thereof defined by the appended claim.

In the drawing, Figure 1 is a perspective View of a milk cooling cabinet constructed in accordance with my 55 invention, a portion being broken away, and

of the cabinets as hereinafter described. Disl0 posed on the frame l is a floor 3, preferably formed of a ply-board and secured in position y in any desired manner under which is arranged a slab of insulating material -4 of `the dry-zeroV4 type ofV insulation, said slab being preferably enl5 closed by a bottom of sheet metal 4', as clearly shown.

Disposed on the floor board 3 between the corner portion 2 is a rectangular container 5 formed of galvanized sheet metal and is herein shown 20 providedwith inclined bottom portions 6 `and l, at its ends terminating in a central horizontal portion 8, on which is seated a central containerv 9, formed of galvanized sheet metal, said cen-- tral container when in position within the con- 25 :y

tainer 5, forms three compartments A, B and C, in the main container 5. The compartments A and C form ice compartments and the compartment B forms a water compartment. A

While in the drawing I have shownrand de- 30 it to be clearly understood that these three compartmentscan be formed by placing partitions 35 within the main compartment 5, and thereforeI do not wish to-limit myself to any p-articular manner of forming thevvarious compartmentsin y the cabinet, as I am aware that they can be formed in various ways without departing from 40 the spirit oi my invention.

The water compartment B is adapted to contain water in which cans of milk are placed so as to maintain the milk at the proper temperature, and this compartment is provided with an overow I 0 into one of the ice compartments and each ice compartment is provided with a'r drain outlet provided with a trap so that the water Y melting from the ice in the ice compartments will drain out of the cabinet without allowing any air to enter the cabinet, whereby remain in a dry condition. v

Suitable filler blocks I2 are disposed on the iioor 3 under the inclined bottom portions 6 and 1 of the container 5 forming a support for the ice 55 the ice will compartments and while in the drawing I have shown the ice compartments provided with integral inclined bottoms, it is, of course, understood that I do not wish to limit myself tothe particular manner of forming inclined bottoms, as I am aware that false inclined bottoms could be inserted in the iceV containers in order to produce a dry ice compartment of such `a construction that the cakes ofY ice would be held by gravity in Y contact with Vthe side walls of thewater com.- p'artments without departing from the spirit of my invention. Y

Slabs I3 and I4 of insulated material'of'the dry-zero type are disposed between`thecorner`- post 2 against the outer surface of the container 5 and these slabs are enclosed by an outer shell ofv galvanized sheet metal I5, which is preferably Yformed of plates secured to the corner post by fastening member I6, such as screws or nails,

although I wish it tobe clearly understood that this isnot essential as other fastening means could beemployed without departing from the spirit of my invention.

The galvanized sheet metal shell I5 is secured to the plate 4 and forms Yan outer casingf'or the complete cabinet, so ask to completelyenclose the insulating'material and protect it from moist as heavy-water proof paper or rubber gasket to break the conductivity of heat between the inside metal. lining, 5, and the outside metal lining, I5,

thereby reducing the heat losses', vand completely Y sealing the insulation material between thein-` nerand outer shells, andforms the top edge of the cabinet, injorder to protect the top edge, and; to prevent its being damaged by the milk'cans a'smthey are inserted and removed from'rthe The cabinet is provided with ahinge'cover formed of a rectangular Y,framejn which is arranged aslab 2I `of;i1,1sulatingV materiallofthe dry-zero type, and the slab is enclosed in a casing ,22 formedY of sheet metal so as tovprotect the insulating material from moisture, and'provide'a rigid 'cover.v The cover is provided with a strip of packing 23, whichy engages the frame I9,1s o,asA

to forman air-tightV joint between the cabinet and cover, whenV the cover is closed,and lwhile I haveV shown oneform of packing, of course, it is understood that various forms of packing could be used without departing from the spirit of my invention.

VThe particular manner of producinga. cabinet in accordance with my invention is disclosed in a companion application which will be led at a later date, asthis invention relates particularly Y to a form with three compartments, namely a central water compartment andrtwo ice compart- Y ments so constructed that the cabinet is provided withan ice compartment at each end having a Alarge capacity and of such a construction that the`l cakes of ice disposed therein will slide down the inclined bottoms'by. gravity, so as to be maintained inl close contact with the side walls of the water compartment at all times, and being in a -fdry-conditionsoas to maintain the water in the f zwater,` compartment at a temperature 7 to 10 degrees F..lower than is possible with other types of' cabinets, which are not provided with means for holdingthe ice while melting in contact with Qthe'walls of the water compartment.

While in the drawing; I have shown certain details Vof construction, I wish it to be clearly understood that I do not wish to limit myself -to any particularmanner of constructing the cabinet, as my invention consists of'producing a milk Y ncooling cabinet of the typewithacentral water compartment" on each Aside of which is arranged an ice compartment so constructed that the ice is maintained in a dry condition and in contact with the walls of the water compartment by gravity,

Vwhereby I amable to increasev the eiliciency of vthe cabinet.V j

What I claim is:

tainer having bottom portions at each end inclined downwardly towards the center and terminating yata central flat-portioman oblong shaped Vinner container arrangedtransvers'ely within the outer container on said Vilat portion,

therarrangeinent forming a water compartment theinclined end portions, said Water compartcompartments providedwith a trap and a cover for closing the outer compartment.
